I've missed the last two Power 9 Challenges, sadly. I need to plan my schedule better. If I had made it, Oath would have performed better.
I'm generally happy for Saheeli Oath to continue to be underrated. If I sideboard correctly and play patiently, I can beat other Gush decks reasonably well.
Meanwhile, Shops is a good matchup if I can counter the first disruption spell (Thorn, Sphere, Revoker, etc.) and either lay down an Oath or get a Dack on the board. White Eldrazi, however, is a real problem: the new Thalia is even more painful than the old Thalia.
If I were to say anything about the results of this challenge, it would be that the MTGO meta is really swingy. People really move back and forth across the archetypes. There are some of us who play one archetype exclusively, or at least 90%+ of the time, but more people seem to really react strongly to the last big tournament.
